"Hank Davis does a terrific job in helping readers understand how ways of thinking that were both reasonable and advantageous in caveman days become illogical - and potentially destructive - when they are overextended to modern times. A stimulating, thought-provoking book!" --Madeleine Van Hecke, author of Blind Spots: Why Smart People Do Dumb Things
"Why do we humans suffer from delusions such as those of religion? Davis gives the best explanation yet. Our brains are still the same as our Pleistocene ancestors whose survival was enhanced by seeing dangers even when they were none there. By critical thinking we can rid ourselves of these no longer needed survival tools." --Victor J. Stenger, author of the New York Times bestseller God: The Failed Hypothesis.
